The least whole number possibility for the third side is 8 cm. The greatest whole number possibility for the third side is 22 cm.

A triangle is a three-sided polygon. It is a geometric shape that has three edges and three vertices. Triangles can be classified based on their side lengths (such as equilateral, isosceles, or scalene) or based on the angles between their sides (such as acute, right, or obtuse). Triangles are a fundamental shape in geometry and are used in many branches of mathematics and physics. To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Using this rule, we can find the possible range of values for the third side of the triangle.

The least possible length of the third side would be:

8.5cm + 15cm - 15cm = 8.5cm

The greatest possible length of the third side would be:

(8.5cm + 15cm) - 1cm = 22.5cm

Step-by-step explanation:

Given: F = 11, C = 11, E=?

By Euler's formula, we have:

\(F + V - E = 2 \\ \therefore \: 11 + 11 - E = 2 \\ \therefore \:22 - E = 2 \\ \therefore \:22 - 2 = E \\ \huge \red{ \boxed{\therefore \: E = 20}}\)

Hence, the solid will have 20 edges.

There are 22 edges for a solid with 11 faces and 11 vertices.

It is concerned with the geometry, region, and density of various 2D and 3D shapes.

Given data;

Faces,F = 11

Vertices,V = 11

Edge,E = ?

From Euler's formula;

F+V-E = 2

11+11-E =2

22-2 =E

E=20

Hence there are 22 edges for a solid with 11 faces and 11 vertices.

The probability that Delta Airlines will receive no complaints on a given day can be calculated using the average number of complaints per day, which is 2.5.

To find the probability of receiving no complaints on a given day, we can use the concept of a Poisson distribution. The Poisson distribution is commonly used to model the occurrence of rare events over a fixed interval. In this case, the average rate of complaints is given as 2.5 per day.

The probability of receiving no complaints can be calculated using the formula P(X = 0) = e^(-λ) where λ is the average rate. Substituting λ = 2.5 into the formula, we have P(X = 0) = e^(-2.5).

Using a calculator or a computer program, we can calculate the value of e^(-2.5) to find the probability. The result will be the probability that Delta Airlines will receive no complaints on a given day.

In a graph, X and Y are two axes that are used to plot data points.

X represents the independent variable and Y represents the dependent variable. The relationship between the two variables is represented by a mathematical equation which is usually represented by a line on the graph. A graph is a visual representation of data in which points on a plane are used to represent values of a particular variable. X and Y are two variables that are typically used in a graph. X is the independent variable, which is plotted on the horizontal axis. It is the input or cause that affects the output or effect, which is represented by Y. Y is the dependent variable, which is plotted on the vertical axis. It is the output or effect that is caused by the input of the independent variable. The equation usually takes the form of y = mx + b, where m is the slope of the line, x is the independent variable, y is the dependent variable and b is the y-intercept of the line. In order to calculate the equation of the line, you must have at least two points on the graph. You then plug in the two points into the equation to calculate the slope and intercept. Once you have the equation, you can plot all the other points on the graph and draw the line.

The probability of selecting a white-tailed deer that carries the Lyme disease bacteria is 1 in 10,000, or 0.0001. This means that out of every 10,000 white-tailed deer on the east coast, only one is expected to carry the Lyme disease bacteria.

If we assume that each deer in the population has an equal chance of carrying the bacteria, then the probability of selecting a deer that carries the bacteria can be calculated using the formula for probability:

Probability = Number of desired outcomes / Total number of possible outcomes

In this case, the number of desired outcomes is one (since we want to select a deer that carries the bacteria), and the total number of possible outcomes is the total number of white-tailed deer in the population. Since we don't know the exact number of deer in the population, we can assume that it is very large, so we can use an approximation:

Probability ≈ 1 / (Very large number)

Therefore, the probability of selecting a white-tailed deer from the east coast population that carries the Lyme disease bacteria is very close to 0.0001 or 1 in 10,000.

1.)  Probabilities range from 0 to 1, denoting impossibility and certainty, respectively.

2.) The sum of probabilities of all possible outcomes is equal to 1.

1.) Individual probabilities will always have values between 0 and 1. This property is known as the "probability bound." Probability is a measure of uncertainty or likelihood, and it is represented as a value between 0 and 1, inclusive.

A probability of 0 indicates impossibility or no chance of an event occurring, while a probability of 1 represents certainty or a guaranteed outcome.

Any probability value between 0 and 1 signifies varying degrees of likelihood, with values closer to 0 indicating lower chances and values closer to 1 indicating higher chances. In simple terms, probabilities cannot be negative or greater than 1.

2.) The sum of the probabilities of all individual outcomes must equal 1. This principle is known as the "probability mass" or the "law of total probability." When considering a set of mutually exclusive and exhaustive events, the sum of their individual probabilities must add up to 1.

Mutually exclusive events are events that cannot occur simultaneously, while exhaustive events are events that cover all possible outcomes. This property ensures that the total probability accounts for all possible outcomes and leaves no room for uncertainty or unaccounted possibilities.

We need to spin the spinner 150 times, to expect a multiple of 4 to be spun 30 times.

In the question, we are given that a spinner is divided into 15 identical sectors and labeled 1 through 15.

We are asked the number of times the spinner must be spun to expect a multiple of 4 30 times.

The possible outcomes of a multiple of 4 are 4, 8, and 12.

Thus, the number of possible outcomes are 3.

The total number of outcomes are 15.

Thus, the probability of getting a multiple of 4 in one spin = 3/15 = 1/5.

Thus, to expect a multiple of 4 once, we need to spin the spinner 5 times.

Thus, to expect a multiple of 4 30 times, we need to spin the spinner 5 * 30 = 150 times.

Omitting the capital variable in a production function is likely to introduce a positive bias on the coefficient of labor, while omitting a variable measuring the probability of precipitation in an equation for concert attendance is likely to introduce a negative bias on the coefficient of the weekend dummy variable.

(c) In a production function for airplanes, if the capital variable is omitted, it is likely to introduce a positive bias on the coefficient of labor. The reason for this is that capital and labor are typically complementary inputs in production, and by omitting the capital variable, the model fails to account for the influence of capital on production. As a result, the estimated coefficient of labor will be higher than its true value, leading to a positive bias. The size of the bias will depend on the extent to which capital and labor are complements in the production process.

(d) In an equation for daily attendance at outdoor concerts, if the variable measuring the probability of precipitation is omitted, it is likely to introduce a negative bias on the coefficient of the weekend dummy variable. The reason for this is that the probability of precipitation at concert time is likely to affect attendance, and by omitting this variable, the model fails to capture its impact. As a result, the estimated coefficient of the weekend dummy variable will be lower than its true value, leading to a negative bias. The size of the bias will depend on the strength of the relationship between precipitation and attendance, as well as the proportion of concerts that are affected by precipitation.

The center of the circle is (-3, -4), and its radius is sqrt(9) = 3.

To determine the center and radius of the circle within the given equation x^(2)+y^(2)+6x+8y=-16, we need to complete the square for both x and y.

First, let's complete the square for x by adding (6/2)^2 = 9 to both sides of the equation:

x^(2) + 6x + 9 + y^(2) + 8y = -16 + 9

Simplifying this equation, we get:

(x + 3)^(2) + y^(2) + 8y = -7

Next, we complete the square for y by adding (8/2)^2 = 16 to both sides of the equation:

(x + 3)^(2) + (y + 4)^(2) = 9

Now we can see that the equation is in standard form: (x - h)^(2) + (y - k)^(2) = r^(2), where (h, k) is the center of the circle and r is its radius.

Therefore, the center and radius are (-3, -4) and 3 respectively.
